TROLLEY.

To all lcho-m 'it may conce/rn.

Be it known that l, EDWARD Y, Moonn, a citizen of the United States,- residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a cert-am new and useful Improvement in 'l`rollcys, of which the following isV a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to trolleys adapted to travel on a suitable support and carry a load. The trolley may or may not be com-Y bined with raising mechanism to make a travelinvP hoist, as desired.

The object of the invention is to increase the. eiiiciency of such trolleys by arranging them so that they may move freely whenever desired, whether the track be straight 6r curved, and may be clamped to such trackv at any point.

The invention resides in the means by which these advantages arev attained, as will be hereinafter described and 'definitely set out in the claims. i

` In the drawings, Figure 1 is an end elevation of'niy trolley, supportedon a suitable I-beam. Fig. 2 is a sectional side elevation of the saine, the plane of the section being indicated by the line 2-2 in Fi 1. Fig. 3 is a cross section in a plane para lel with Fig. 1, on the line 3-3`on Fig. 2. Fig. 4 is a sectional plan taken just above the lower flange of the I-beam, as indicated by the line 4--4 in Fig. 2.

`Referring to the parts by reference minierals, 10 represents an I-beam support, on the lower flange 9 of which the trolley rides. The frame of the trolley is shown as composed of a pair of members extending onto opposite sides of the I-beam and connected together beneath the' I-beamf The frame may thus be described as being generically of As shown, it has portions 1,1 which are opposite the web'of the I-beam and are inclined parallel with the normal to the top surface of the flange 9 ofthe I-beam. At their lower edges, these side members 11 continue outwardly and then downwardly in the ofiset portion 12, and then'lnwardly, as

shown at -13 beneath the I-beam, and finally downwardly as shown at 14, where they are held together by bolts 15.

19 represents a suitable supporting eve, which is shown as' carried Vby the trolley frame, beneath the I-beani. This is to be taken as illustrative of any load supporting Specification of Letters Patent.

f device which is carried by or mounted on the trolley.

'Ihe trolley is supported by wheels 16, whichride on the lower fiange 9, being mounted on studs 18 carried by the portions 11 of the frame. These wheels 16 arel iiangeless.

By reason of these wheels being inclined and standing normal to their inclined support, as shown, they tend to properly center the trolley on the support.

'lo insure against-lateral displacement or binding, I provide guide rollers 20, mounted on vertical pins21. These rollers are located in the offset portion of the frame, the upper ends of the pins extending into the frame approximately at points where itbends outwardly, andthe lower ends extending into the horizontal portion 13 of the frame.

l hese rollers ride against the vertical edge of the I-beam flange 9. This constructionI enables the hoist to. freely pass around curves without binding, which has heretofore resulted from flanges on thel supporting wheels. Moreover, such flanges have always been a source of wear, which my hoist avoids. construction is simple and is capable ofembodiment in a very compact form, as shown.

lHaving thus described my invention, I claim:

1. The combination with atrackway supported from above, of a trolley having wheels riding on' aange of the tr'ackway, the trolley extending transversely beneath such flange, and guide wheels carried by the trolley and adapted to engage the edge of the flange.

2. The combination with an I-beam, of a trolley having a frame extending beneathv the I-beam and above vits lower Harige,

wgheels carried by the upward extensions'of the frame and adapted to ride on such flange, and other wheels carried by the frame and adapted `to engage the edge of the I-beam.

3. In a mechanism adapted to travel on the lower fiange of an I-beam and extend transversely beneath the beam, in combination, a frame, supporting wheels carried thereby adapted to ride'on such flange, and guiding wheels carried thereby adapted to engave the edge of the ange.-

4. the lower ange of an I-beam, the combination o f a frame. adapted to extend beneathv such I-beam and onto the opposite sides thereof, angeless supporting wheels carried by said frame, and a apted to track on the T he DIn a mechanism adapted to travel on 5. In a mechanism adapted to travel on the lowerklange of an I-beam, the eombinaf tion of an approximatel posite sides thereof, langeless supporting U-shaped [rame extending beneath the I- eam and onto opwheels carried on the inner sides of the side members of the frame and meinung out-'3 wardly, and rollers carried on vertical pins mounted in the frame and adapted to engage the edge of the flange.

6. In a mechanism of the character dcing beneath its points of support, load supbeing offset outwardly beneath the studs,

and then extending inwardly beneath the supporting wheels and guiding wheels carried by the frame in said odset portion.

9. In a mechanism adapted to travel on a depending track, the combination of an approximately U-shaped frame extending beneath the track and onto opposite sides thereof, supporting wheels carried on theA inner sides of the side members of the frame, the frame being offset below such wheels, and rollers carried on vertical pins mounted in the frame at such offset portions and adapted to engage the track.

10; In a mechanism adapted to travel on the lower flange of an I-beam, in combination, a frame, supporting wheels carried on the inner sides of the frame and inclining outwardly, and adapted to ride on such ange, and guiding wheels carried by the frame on vertical journals and adapted to engage the edge of the flange the framefbeing brou 4ht inward beneath the guiding wheels.` and eneath the I-beam flange.

11. The combination of a mechanism adapted to travel on the lower flange of an I-beam, comprising a frame made in two parts, each part having an upwardly projecting side plate, a lateral portion and a downward portion, the two lateral portions coming together beneath the I-beam flange and being secured by such downward portion,supporting wheels carried by the upwardly projecting portions of the frame, and

g guide. wheels carried intermediately by he scribed, the combination of a frame extendl frame and engaging the edge of the Hai 12. ln a mechanism ot the character scrlbed, the combmatlon of a substantiall l U-shaped l'rznm, a pair of supporting whee s carried by the upwardly projecting side members ot the frame on their inner sides, there being space between the wheels for a track support, and space beneath the wheels and above the intermediate portion of the frame for the track, and guide Wheels carried by the frame above such intermediate p0rtion and adapted to engage the edge of the track.

13. 'lhe combination of a frame having side members, studs carried by the side members, supporting Wheels journaled on the studs, the frame extending transversely from one side to the other beneath the supporting wheels and lateral guide wheels carried by the frame adjacent to the edge of the trackway.

14. The combination of a frame having side members, studs carried by the side members, supporting wheels journaled on the studs, the frame extending transversely from one side to the other beneath the supporting wheels and lateral guide wheels carried by the frame adjacent to the edge of the trackway, said guide wheels being mounted on vertical pins, the prolongation of whose axes substantially intersect the axes of the studs.

In testimony whereof, I hereunto affix my signature in the presence of two witnesses.
